Technically XenServer/XCP comes with a minimal, optimized OS, based on
Centos, as dom0.
While there may be some performance improvement, I would not expect
something drastic.

Did you install PV drivers? Xenserver has its own PV drivers. When
using Centos/Xen you can use GPLPV. WIthout PV drivers, Windows disk
and network I/O will be slow.

If by "shutdown Centos" you mean shutdown the dom0, then no, it's not possible.

If your ONLY concern is Windows domU performance, I suggest you try
James Harper's GPLPV before trying anything else :
http://www.meadowcourt.org/downloads/. When used with stock Centos Xen
version (3.1+), I suggest you use 0.10.x version as I had some problem
with 0.11.x version.
